Windows 10 SDK preview build 17661 now available for developers

Microsoft may have developers fully focused on Build 2018 this week, but it has managed to slip a new SDK preview build out as well. Following up on last week's release of the first Redstone 5 build for Fast ring Insiders, Microsoft today quietly shipped its accompany SDK with preview build 17661 (via Neowin).

This is the first Redstone 5 SDK, but it's currently unclear what is new. Microsoft typically releases a blog post covering the new aspects of each SDK release, but one isn't available just yet. Presumably, we'll learn more about new APIs and features as Build 2018 wears on.
